SKC Coated Filters make sampling reactive compounds fast and easy. They are a convenient alternative to wet chemistry methods using impingers. Simply unplug the lightweight cassette, insert it into an SKC Filter Cassette Holder, clip holder to a worker’s collar, and attach to a personal sample pump. Use coated filters to collect compounds that exist as an aerosol or mist or for some higher boiling vapors. Flow rates are typically greater than 1 L/min and sampling times range from 15 minutes to one hour. Most coated filter samples are extracted in solvents and analyzed by gas or liquid chromatography. SKC offers coated filters to meet a variety of OSHA, NIOSH, ASTM, and international agency methods.

ISO-CHEK Coated Filter System Developed for Isocyanates
Traditional methods for isocyanate collection (NIOSH Method 5521 with impinger and OSHA 42 with 1-2PP impregnated filter) yield samples that are susceptible to degradation under ambient conditions, require time-consuming sample preparation, and can provide ambiguous results. The IRSST (Institut de recherché Robert-Sauvé en santé et en sécurité du travail du Québec) minimized these problems by developing and patenting the ISO-CHEK Sampling System. The ISO-CHEK dual-filter cassette captures isocyanate aerosols and vapors simultaneously and separately at the point of collection. This collection method is highly stable, allows rapid sampling, and provides for highly sensitive physical and chemical characterization of isocyanates.
